Powder-actuated rod hanger clips consist of a 90 degree L shaped fastener with an angled flange attached to the end of the longer leg. The shorter leg has a threaded hole which allows a threaded rod to be attached. A powder-actuated pin is attached to the flange of the fastener and is used to fasten the clip to various surfaces. They are primarily used in applications where a threaded rod needs to be attached to concrete or masonry.
